JETAIRE PATENTS FOAM SOLUTION FOR AIRCRAFT FUEL TANK SAFETY



Jetaire has announced that its Invicta reticulated foam ignition mitigation system is now patented technology. The solution for the FAA’s Fuel Tank Flammability Reduction (FTFR) rule was officially patented in late December 2017 and Jetaire says this solidifies its position as leaders in understanding the scope and depth of the technology. Invicta is the only patented foam-based solution for the requirements of the fuel tank flammability reduction rule and brings aircraft into


The company began the design process on Invicta in 2008.  The product works as a passive system to fill the oxygenated space in a fuel tank to suppress fuel ignition.   The Invicta system is advantageous to other inerting solutions because of its simplicity. Designed with a light-weight, electrically conductive, reticulated polyurethane foam, Invicta is a three-dimensional skeletal matrix that suppresses ignition propagation caused by sparks including a lightning strike or static discharge. Additionally, Invicta inhibits movement of fuel within a tank, which could result in a spark through changes in weight distribution and friction. A spark introduced into a tank that incorporates the Invicta foam will produce nothing more than a wisp of smoke.


Once Invicta is installed it is essentially maintenance-free and its components do not have a life limit. Installation time depends on the model of aircraft, but the process is typically 2-4 days for a narrow body and 4-5 days for a widebody.  The installation is quicker and simpler than other products on the market for fuel tank inerting, leading to reduced disruption and aircraft downtime. 


Although the company declined to share pricing information, it says the Invicta kit and installation are cost effective and affordable. Invicta is currently FAA-certified for Boeing 737, 737NG, 757 and 767 aircraft as well as the Airbus A320 family. A spokesperson for Jetaire says the company is nearing completion of certification for the Boeing 777 and it has applied for EASA approval for existing Supplemental Type Certificates (STC).
